His song, Heroes, by songwriter Anton Malmberg Hård af Segerstad, has certainly been making the rounds in Stockholm's clubs this spring. But most of all it was Zelmerlöw's stage show that no doubt played a part in his sweeping victory in the competition.

In the act, the singer interacts with a series of digital effects surrounding him – even landing a fist bump perfectly with... yes, you read it right, a digital gnome.

It is worth noting that the performance has not been completely uncontroversial and Zelmerlöw's gnome army has been accused of plagiarism, leading the singer's crew to tweak the background digital effects.

Zelmerlöw follows in the footsteps of several other of his countrymen as a Eurovision winner.

Sweden is one of the most successful Eurovision competitors, with previous winners including Abba in 1974, the Herreys brothers in 1984, Swedish icon Carola in 1991 and Charlotte Nilsson with 'Take Me to Your Heaven' in 1999.

More recently, Sweden saw young star Loreen take home the heavily sought out award for her song 'Euphoria' in 2012.

The host country Austria came joint last with HGermany with zero points, just edged out by the U.K. which managed five points.
